Contrary to popular rumor, Rhinos can, and do, back up. It is not a graceful business, but it does sometimes get us where We need to go.
Nature did not design Us to easily peer past our own grandiose amplitude. Thus, when confronted with situations demanding reverse gear, We have minor misgivings. We prefer to turn and move out.
Kangaroos cannot go backward, We are told. For all Rhinos know, it’s true.
